I tend to use parens and & on my functions.
I think it makes it easier on whoever has to read my code next.
The parens remove any perceived ambiguity(sp?) about function
params and the & clearly seperates which functions I've written
from any built in ones.
IIRC there was some difference about using the & in Perl 4,
something to do with the order in which perl tried to find
the code for it, or something. (perhaps merlyn will clear
this part up).
